DETAILED DESCRIPTION OF THE INVENTION

Different examples of the present invention are described below with reference to the drawings, wherein the same reference numerals indicate the same elements. The embodiments described in the text below will facilitate those skilled in the art to have a thorough understanding of the invention, but they only intend to illustrate instead of limiting the invention. The elements, components, modules, devices and means in the figures are not necessarily drawn to scale, but they only schematically show the relative relationship among said elements, components, modules, devices and means.

A wearable device is a portable device that can be directly worn by a user or be integrated into clothes or accessories of a user. A wearable device that uses the wrist as a support is taken as an example in the text below to illustrate the present invention, but it does not mean to exclude wearable devices that use the head as a support (such as glasses) and the wearable devices like smart clothes. In practical application, the technical solution proposed by the present invention can be applied to glasses, necklaces, armlets, etc. In addition, the wearable device that uses the wrist as a support is specifically exemplified by a bracelet or wristwatch having a display screen.

In the following descriptions, the wearable control device according to the example of the present invention is used for controlling a smart home, that is, the controlled appliances controlled by said wearable control device are various appliances of a smart home. As those skilled in the art may understand, a smart home may include many components like security protection, light control, curtain control, gas valve control, information household appliance, scene linkage, floor heating, healthcare and epidemic prevention, but the appliances specifically involved in each smart home system are not completely the same because of different users, so only several appliances are involved in this text as examples.

FIG. 1 is a schematic drawing of the structure of a wearable control device for controlling a controlled appliance according to one embodiment of the present invention. As an example, the wearable control device 1 as shown in FIG. 1 is a wearable device using the wrist as support. The wearable control device 1 comprises a power unit 10, a biological information input unit 12, a processing unit 14 and a first communication unit 16. Alternatively, the wearable control device 1 may comprise a presetting unit 18 and a second communication unit 20 as well as a warning unit 22.

The power unit 10 supplies power to each of the units and components of the wearable control device 1, and it can be storable power of any forms, for example, a battery, that can store power and output the stored power to each of the units and components of the wearable control device 1, where said battery, for example, could be a rechargeable battery.

The biological information input unit 12 receives the biological information input by the user. In the present invention, the biological information may be various biological information related to an individual user, such as fingerprint information, facial information, voice information, iris, etc. When the biological information is fingerprint, the biological information input unit 12 is, for example, a fingerprint sensor; when the biological information is facial information, the biological information input unit 12 is, for example, a camera; when the biological information is voice information, the biological information input unit 12 is a voice input unit, for example, a microphone, etc. In all examples herein, the fingerprint information is used as the biological information. In the descriptions below, the biological information input unit 12 sometimes refers to a fingerprint sensor 12 according to the context.

The processing unit 14 determines whether the biological information received by the biological information input unit 12 is registered biological information, and generates a control signal based on the biological information only when said biological information is registered biological information. For example, the processing unit 14 first determines whether a user fingerprint input through the fingerprint sensor 12 is a registered fingerprint. If yes, it further generates a corresponding control signal based on the input fingerprint. According to one example of the present invention, the processing unit 14 compares the input fingerprint to the registered fingerprint and generates a control signal according to a correspondence between the preset fingerprint and the control signal.

The first communication unit 16 sends the control signal generated by the processing unit 14 to a controlled appliance so as to control said controlled appliance. The first communication unit 16 also receives signals from the controlled appliance. As mentioned previously, the exemplified wearable, control device 1 can be used to control a smart home system, so alternatively, the first communication unit 16 sends the control signal to a control center of a smart home system, and the corresponding controlled appliance is controlled by the signal.

The correspondence between the fingerprint and the control signal is pre-set. For example, it is pre-set that the fingerprint of the index finger of the right hand of user A is associated with light control, then if what has been input is the fingerprint of the right hand index finger of user A, control of the light is enabled. The control to the light includes turning on the light if the fingerprint of the right hand index finger of user A is received while the light is off, and turning off the light if the fingerprint of the right hand index finger of user A is received while the light is on. Further, if two inputs the fingerprint of the right hand index finger of user A is received successively while the light is on, it indicates that brightness of the light will be adjusted. It is pre-set that the fingerprint of the index finger of the left hand of user A is associated with curtain control, then if what has been input is the fingerprint of the left hand index finger of user A, control of the curtain is enabled. Specifically, it can be further set to close the curtain if the fingerprint of the left hand index finger of user A is received while the curtain is open, and to open the curtain if the fingerprint of the left hand index finger of user A is received while the curtain is closed. The correspondence between the fingerprint and the control signal can be set in various different forms, but it is not limited to that described above.

According to an example of the present invention, the wearable control device 1 comprises a presetting unit 18 coupled to the biological information input unit 12 and the processing unit 14. When the wearable control device 1 is in a preset mode, the presetting unit 18 sets a correspondence between the biological information input through the biological information input unit 12 and the control signal. For example, in a preset mode, the wearable control device 1 first determines whether to set the fingerprint received through the biological information input unit 12 as a registered fingerprint, and when it determines to set the fingerprint as a registered fingerprint, it further sets a correspondence between the fingerprint and the control signal. The determination of whether to set the fingerprint received through the biological information input unit 12 as a registered fingerprint is carried out based on safety principle. In an example of the present invention, becoming a registered fingerprint requires approval from an administrating user, where the administrating user herein refers to a user having the right to determine whether to register a new fingerprint as a registered fingerprint, who could also be referred to as the administrator of the wearable control device 1. Taking a family as an example, when there are three family members (user A, user B and user C), user A is an administrating user, and the other two members can input their fingerprints through the wearable control device 1 for registration, but user A determines whether the registration can be successful. For example, in a registration mode, user B first input his/her fingerprint through the biological information input unit 12, if user A agrees to accept him/her as a registered user, then user A input the fingerprint of the right hand thumb through the biological information input unit 12 to indicate approval.

According to another example of the present invention, the wearable control device 1 comprises a second communication unit 20. The second communication unit 20 enables communication between the wearable control device 1 with an external electronic device. The external electronic device may comprise a wearable device control unit. In a preset mode, the presetting unit 18 sends a signal of a user requesting registration of the biological information to the wearable device control unit through the second communication unit 20, and, after obtaining a confirmation from the wearable device control unit, sets the biological information as registered biological information and further sets a correspondence between the biological information and the control signal. The external electronic device is, for example, one or more of a cell phone, a tablet PC and a laptop of the administrating user of the wearable control device 1. For example, in a preset mode, user B first inputs his/her fingerprint through the biological information input unit 12, and the second communication unit 20 of the wearable control device 1 sends a signal of user B requesting registration to an electronic device, e.g. a cell phone, of user A. If user A agrees, user A may sends a signal of approval to the second communication unit 20, where said signal of approval is, for example, a set of confirmation codes.

According to still another example of the present invention, the wearable control device 1 further comprises a warning unit 22. The warning unit 22 issues a warning signal when the received signal from the controlled appliance is an alarm signal. The warning unit 22 warns, for example, by vibration, or by a display visible to the user, or by a voice audible by the user, or by a combination of any of said ways. Generally speaking, a smart home includes an armed mode and a disarmed mode. In an armed mode, if someone intrudes into the environment where the smart home is located, an alarm signal of the smart home system is communicated through the first communication unit 16 to the wearable control device 1, and the warning unit 22 then issues an alarm signal. The meaning of the armed mode and disarmed mode is just the same as that commonly understood by those skilled in the art. With respect to a smart home system, when the user leaves home, the smart home system is put into an armed state, and when someone intrudes, the system will give an alarm; the disarming system is to remove the arming when the user returns home.

According to an example of the present invention, the wearable control device 1 comprises a display unit, a key for selecting controlled scenes, and a key for enabling setting of arming and disarming. Controlling scenes refers to controlling different appliances in a smart home system, for instance, scene 1 is controlling the light, scene 2 is controlling the air conditioner, scene 3 is controlling the curtain, and scene 4 is controlling the gas valve, etc. When the user selects a scene, the display unit of the wearable control device 1 will display the scene that is currently selected, if it is not the scene that the user wants to select, then the user can select the desired scene through the key for selecting control scenes. Referring to the descriptions about the correspondence between the fingerprint and the control signal as given in the above text, the correspondence between the fingerprint and the control signal herein can also involve the scenes. For example, in scene 1, the fingerprint of the right hand index finger of user A is associated with light control, while in scene 2, the fingerprint of the right hand index finger of user A is to control the air conditioner.

In addition, the preset mode can be entered in different ways, for example, the preset mode is entered by selecting in a main menu (if any) of the wearable control device 1; or it is entered through a mode selecting key disposed on the wearable control device 1, for example, while the mode selecting key may be either a separately arranged key or a certain existing key.

In the various examples described herein, the first communication unit is, for example, a transceiver configured to be able to communicate with the controlled appliance, and its operating frequency band can be set according to the actual need. The first communication unit can be a communication module operating in 315M or 433M as described in the examples below, or it can be a wireless module having such functions as Bluetooth and NFC, as long as it can communicate with controlled appliances. The second communication unit is a transceiver configured to be able to communicate with the external electronic device, for example, it can be a communication module operating in the frequency band of 2.4 GHz or under the protocol of 802.15.4 as described in the examples below, or it can be various communication modules that can communicate with the external electronic device in other frequency bands or under other protocols. Although the present invention mentions the first communication unit and the second communication unit, it is not excluded that the first communication unit and the second communication unit are configured as the same communication module. For example, both the first communication unit and the second communication unit are configured as a Bluetooth module. In such case, the wearable control device controls the controlled appliance through the Bluetooth module and communicates with such external electronic device as a cell phone through the Bluetooth module. Besides, if the wearable control device does not need to communicate with the external electronic device, the second communication unit is unnecessary. For example, in the circumstance as mentioned previously, i.e. “user B first inputs his/her fingerprint through the biological information input unit 12, if user A agrees to accept him/her as a registered user, user A then input his/her fingerprint of the right hand thumb through the biological information input unit 12 to indicate an approval”, the administrating user does not need to send a confirmation information through the external electronic device, and thus the second communication unit can be omitted.

As an example, the wearable control device for controlling controlled appliances according to the example of the present invention can control the smart home system of HGW2000 of Honeywell that is available from the market. In the case of controlling HGW2000, the first communication unit of the wearable control device 1 is configured as a communication module operable in 315M or 433M, and the second communication unit is configured as a communication module operable in a Bluetooth mode or in various frequency bands or protocols that can enable communication with the external electronic device, such as a frequency band of 2.4 GHz or a protocol of 802.15.4. Said wearable control device may include a scene selecting key, an arming/disarming key, and each of the keys can be reused, for example, a specific key can be long pressed for two seconds to enter into the scene selecting mode, and for five seconds to set an arming. Further, the wearable control device can interact with the remote controller (if any) of the HGW2000 system through the first communication unit.

As an example, said wearable control device 1 may also have functions like step counting, sleep detection, time display, etc., just as those smart bracelet currently available in the market. But this is not the focus of the present invention, which will not be elaborated herein.

The wearable control device for controlling controlled appliances according to the present invention can facilitate a user wearing it to directly control various household appliances through the wearable control device without the need to find the controllers. Moreover, the wearable control device according to the present invention can realize control to appliances through input of biological information such as a fingerprint. Besides its convenience, the biological information like a fingerprint is registered only under permission of an administrator of the wearable control device, thus preventing unauthorized user to control the smart home. Furthermore, the wearable control device interacts with the smart home through the first communication unit, when an illegal intruding is carried out in a family or other environment where the smart home is disposed, the smart home system will send a signal to the wearable control device, which will then alert the user by means of vibration or the like, where alerting by means of vibration is greatly advantageous for hearing-impaired users. In addition, in some emergent cases, e.g. being robbed and having the need to send an alarm, the user can directly operate the safety protection system of the smart home through the wearable control device to send an alarm, so as to call the police in a faster and more undetectable way.

According to another aspect of the present invention, a control system for controlling a controlled appliance is provided. FIG. 2 is a schematic drawing of the control system. The control system comprises a wearable control device 2 and an external electronic device 5. The external electronic device 5 comprises a wearable device control unit 50. The wearable control device 2 comprises a power unit 20, a biological information input unit 22, a processing unit 24, a first communication unit 26 and a second communication unit 30. Alternatively, said wearable control device 2 further comprises a presetting unit 28. Alternatively, said wearable control device 2 further comprises a warning unit 32.

The power unit 20 supplies power to each of the components and units of the wearable control device 2. The biological information input unit 22, the processing unit 24 and the first communication unit 26 are basically the same as the biological information input unit 12, the processing unit 14 and the first communication unit 16 as shown in FIG. 1, so they will not be elaborated any more. The wearable control device 2 interacts with the external electronic device 5 through the second communication unit 30. When the wearable control device 2 is in a preset mode, it sends, through the second communication unit 30, a signal requesting registration of the biological information input through the biological information input unit 22 to the wearable device control unit 50, and sets the biological information as registered biological information after obtaining a confirmation from the wearable device control unit 50.

According to one example of the present invention, the wearable control device 2 may further comprise a presetting unit 28. In a preset mode, if the biological information that requests registration has already obtained confirmation from the wearable device control unit 50, then the presetting unit 28 can set a correspondence between said biological information and the control signal. Thus in a non-preset mode, the processing unit 24 generates a control signal based on said biological information if the received biological information is the registered biological information.

Alternatively, according to one example of the present invention, said wearable control device 2 may further comprise a warning unit 32 for issuing a warning signal when the received signal from the controlled appliance is an alarm signal.

Similar to the descriptions given above with reference to FIG. 1, the external electronic device 5 is, for example, one or more of a cell phone, a tablet PC and a laptop of the administrating user of the control system. In the example shown in FIG. 2, as for how the fingerprint is registered, how the administrating user responds to the registration request through the external electronic device based on the confirmation, how the preset mode is entered, and how the configuration and operation of the warning unit 32 is like, these are similar to the ways described in the above with reference to FIG. 1, so they are not elaborated any more.

According to still another aspect of the present invention, a method for controlling a controlled appliance is provided. The method is performed in a wearable electronic device that comprises a biological information input unit. There are different biological information input units because the biological information adopted differ. In this example, the biological information is a fingerprint, accordingly, the biological information input unit is a fingerprint sensor.

The components of either the wearable control device as shown in FIG. 1 or the control system for controlling a controlled appliance as shown in FIG. 2 can be implemented by hardware, software or by a combination of hardware and software. In short, the power unit 20 can be a rechargeable battery, the communication unit can be a transceiver or the like, the processing unit can be a microcontroller or other components that can realize control function, and the warning unit can include a vibrator. If the present invention is to be implemented on an existing smart bracelet, then a biological information input unit as well as other necessary hardware like a processor may be added to the smart bracelet. As an alternative, a biological information input unit may be added, while other units, such as the processing unit, may be implemented by configuring existing functions of the bracelet by means of software.

FIG. 3 is a flow chart of a method for controlling a controlled appliance according to an example of the present invention. In step 300, the biological information input by a user through the biological information input unit is received. For example, the wearable electronic device receives fingerprint input by the user through the biological information input unit.

In step 302, the wearable electronic device determines whether the received biological information is registered biological information, and generates a control signal based on said biological information only when the received biological information is registered biological information. As an example, the wearable electronic device first determines whether the fingerprint of the user input through the fingerprint sensor is a registered fingerprint. If yes, it further generates a corresponding control signal according to the input fingerprint. For instance, the wearable electronic device compares the input fingerprint to the registered fingerprint and generates a control signal according to the correspondence between the preset fingerprint and the control signal.

In step 304, the wearable electronic device sends the generated control signal to the controlled appliance. When the methos is applied in the situation where the controlled appliance is an appliance of a smart home system, the wearable electronic device can also send the control signal to a control center of the smart home system.

In step 306, when there is a signal from the controlled appliance, the wearable electronic device may receive the signal and process accordingly, such as acting as instructed by said signal. As an example, the controlled appliance can send an alarm signal to the wearable control device, and said wearable control device issues a warning signal in the form of display, vibration, voice or a combination thereof, for example.

According to an example of the present invention, the method shown in FIG. 3 further comprises setting a correspondence between the biological information input through the information input unit and the control signal when the wearable control device is in a preset mode. Thus the generation of the control signal in step 302 is based on the preset correspondence.

For example, in the preset mode, a user that requests registration first input his/her fingerprint through the biological information input unit. If the administrating user agrees to accept him/her as a registered user, then the administrating user inputs the fingerprint of his/her own right hand thumb through the biological information input unit to indicate approval. Alternatively, the wearable control device can communicate with an external electronic device including a wearable device control unit. Specifically, the wearable control device sends a signal requesting to convert an input fingerprint into a registered fingerprint to the external electronic device, and if the administrating user agrees to accept said fingerprint as a registered fingerprint, then confirmation information is generated through the wearable device control unit of the external electronic device and is sent to the wearable control device, and the wearable control device accordingly sets the biological information as registered biological information and sets the correspondence between the biological information and the control signal.

The method shown in FIG. 3 can be carried out in the wearable electronic device as shown in FIG. 1. The method shown in FIG. 3 can be implemented in various smart bracelets currently available in the market, as long as a biological information input unit is added thereto. Even if no biological information input unit is added to the various smart bracelets currently available in the market, as long as they can communicate with a peripheral biological information input unit so as to be used in cooperation with the biological information input unit, then the method shown in FIG. 3 can still be implemented therein.

By carrying out the flow chart of the method for controlling a controlled appliance according to the present invention, the wearable device can be implemented as a wearable control device that can control a smart home, thus facilitating the user wearing it to directly control various household appliances of the smart home through the wearable device without the need to find the controllers. Moreover, control of appliances can be realized through input of biological information such as a fingerprint, so besides convenience, control of the smart home by an unauthorized user is prevented. Furthermore, the wearable control device interacts with the smart home through the first communication unit, when an illegal intruding is carried out in a family or other environment where the smart home is disposed, the smart home system will send a signal to the wearable control device, which will then alert the user by means of vibration or the like. Besides, the alerting by means of vibration is greatly advantageous for hearing-impaired users. In addition, in some emergent cases, e.g. being robbed and having need to send an alarm, the user can directly operate the safety protection system of the smart home through the wearable control device to call the police in a faster and more undetectable way.

Although the specific embodiments of the present invention have been disclosed in the above text with reference to the drawings, those skilled in the art shall understand that the disclosed specific embodiments can be changed or modified without departing from the spirit of the present invention. The embodiments of the present invention are only for illustrating but not for limiting the invention. For example, as for a smart bracelet available in the market, a biological information input unit can be added thereto and the communication interface of the smart bracelet can be configured, e.g. configuring a first communication interface thereto so that the bracelet can communicate with appliances of the smart home.
